Plug-in hybrid electric vehicle is a new type of automotive power system, it can be externally charged to achieve pure electric mode driving, when the battery is exhausted, it can also be in hybrid mode (mainly internal combustion engine) driving, and timely to charge the battery. This kind of car not only takes into account power and fuel consumption, but also enjoys preferential policies in most cities, and plug-in hybrid electric vehicles are a good choice for pure electric vehicles with short driving range.
Plug-in hybrid electric vehicles are mainly divided into three types, which are series plug-in hybrid, gasoline-electric hybrid and extended-range hybrid. Among them, series plug-in hybrid, also known as extended range, the engine does not directly drive the car, the engine needs to drive the generator to generate electricity, and then power the motor to drive the car, the energy transmission chain is long, the overall efficiency is not high. The representative models are BMW i3 extended-range.
Parallel plug-in hybrid power is the most widely used type at present, the type of engine and motor can drive the car, more power transmission mode, better power performance, simple structure, is the mainstream technical route. The representative models are BYD Tang DM.
In general, a plug-in hybrid electric vehicle is a vehicle that integrates a variety of power systems in one, which can not only achieve pure electric mode of driving, but also drive the car through the internal combustion engine, which can not only meet the needs of urban driving, but also solve the problem of short driving range of pure electric vehicles. For consumers, choosing a plug-in hybrid electric vehicle is a good choice.
